Application filed July 19, 1920. Serial No. 397,243.

This invention relates to the manufacture of shoes and more particularly to heel seat fitting machines.

In the manufacture of such shoes as are rovided-witih wooden heels it is necesbefore the heel is attached to trim away a part of the heel seat portionof the sole of the shoe in order to conform the sole to the concave heel seat portion of the This is known as heel seat fitting. Ditferent individual wooden heels, even those of the same lot and intended to be of the same size, may vary considerably in size and shape. It is desirable, accordingly, in order toproduce high grade work on such shoes, to fit each wooden heel individually to the particular shoe to which it is to be attached. When, as has heretofore.

been the general practipe, this operation is performed by hand the operative ordinarily applies the wooden heel to the heel seat portion of the sole of the shoe to which it is to be attached and, using the heel itself as a guide, makes a mark or a pair of marks upon the sole of the shoe to indicate the exact position which the breast of the heel occupies. Then he removes the heel and trims away a part of the heel seat portion of the sole of the shoe with a knife, forming a more or less U-shaped bevel extending from the position of one heel breast corner to that of the other around the heel seat portion of the sole, and provided with a pair of shoulders forming an abutment against which the breast corners of the heel are placed when the heel is attached.

In view of the foregoing, of this invention to provide an improved machine which, without sacrificing the advantages of any of the machines heretofore devised, will further facilitate the perform ance of heel-seat-titting operations, in order that such operations may be performed more accurately, more quickly and otherwise more iconomically and satisfactorily than heretoore. In the attainment of this object, features of theinvention reside in means for supporting the periphery of the heel seat portion of the sole of a shoe while leaving the center of the sole unsupported, together with means for pressing against the center of the heel seat portion to distort the heelseat to render it concave for the action of heel seat line,

it is an object trimming knives. In accordance with this and othenfeatures, the illustrated supporting means comprises a plurality of thinedged adjustable plates constructed and arranged to conform substantially to the sides and the rear of a shoe and adapted to enter the rand'crease of the shoe, to protect the upper from the knives and at the same time to support the periphery of the sole while a presser member is provided for depressing the center of the heel seat portion of the sole and offsetting its periphery upwardly. This allows the knives to form a U-shaped bevel around the heel seat portion by cutting inwardly from the edge toward the tread surface while moving in a path substantially parallel to the plane of the tread surface of the sole, thus providing a simple but efiective organization.

Another featureof the invention consists in the provision of a series of knives operated automatically in sequence to trim the periphery of the heel seat portion of the sole of a shoe.- The illustrated knives are arranged to make overlapping cuts, a knife located at the back of the shoe being preferably operated first and then opposite knives at the sides of the shoe being moved inwardly in pairs successively to form a bevel continuous throughout the range of operation of the knives.

Another object of this invention is to provide improved means for obtaining the desired shoulder formation at the heel breast which will correspond to the shape of the-breast of the heel andwhich will not tend to stretch or otherwise distort the sole of the shoe. With this object in view I provide a support for a shoe and cutting means movable inwardly across the shoe bottom, the cutting means preferably being constructed and arranged simultaneously to bevel the adjacent'portion of the sole. In the illustrated embodiment of my invention, two shoulder-cutters are provided, movable toward one another, to form shoulders on opposite sides of the sole.

To provide for the proper formation of the shoulders, and at the same time to subdivide the chips cut from the periphery of the sole, certain of the knives, including the shoulder-cutters, are provided with angularly arranged cutting edges, and in order further to facilitate the formation of the desired shoulder cut-s, provision is made for varying the position of the angular cutting edges'of the shou]dent-utters longitudinally of the sole and angularly with respect to the sole during their transverse cutting action, to form a curved shoulder.

In accordance with another feature of .the invention. the illustrated rand crease plates at the sides of the shoe are provided with indicating means comprising marks arranged in predetermined relation to the cutting means to facilitate the correct positioning of the shoe in the machine. In using the illustrated machine, it is contemplated that, advantageously, the operative will ii-st mark the position which the heel is to occupy upon the sole of the shoe just as in performing the operation by hand, and then position the shoe in the machine with the mark or marks thus made in alinement with the indicating marks of the machine, whereby the correct positioning of the shoe in the machine is assured and the extent of the trimining may be correctly regulated. The novel shoe supporting means of the machine, which are adjustable for length and breadth, permit such a positioning of shoes of various sizes.

Preferably, and as illustrated, indicating marks disposed in angular relation to one another are provided arranged to be regis-.

tered respectively with corresponding marks upon soles of shoes designed to have various types of heels.

Still further to adapt the machine tofitting the heel seats of shoes designed to have heels differing in the curvature of the heel breast, the illustrated. machine is provided with a pair of opposed knife-guides of one curvature, for example designed to conform to the curvature of a heel having a straight or substantially straight heel breast, and a second pair of opposed knife-guides having a curvature different from the curvature of the guides of the first pair, the pairs of guides being constructed and arranged to be used alternatively to guide sole-trim ming knives transversely of the shoe sole at theheel breast line.

With these and other objects and features in viewthe invention will now be described in connection with the illustrative machine of th accompanying drawings, and pointed out in the appended claims. 7

In the drawings,

Fig. 1 is a perspective view of the illustrative machine with certain portions broken away more clearly to show the construction thereof;

Fig. 2 is a perspective view on alarger scale of a portion of the machine. showin the cutters and their relation to a shoe whic i has been operated upon andjtowhich a heel re firing a straight breastfcpt'is-to b -35;

Fig. 3 is-a plan view showing the relation of the cutters to a shoe, to which a heel rcquiring a curved breast cut is to be attached, before the performing of the heel seat fitting operation and showing also the relation of the indicating marks of the machine to an indicating mark on the sole of the shoe; Figs is a longitudinal section through the heel portion of a shoe showing the relation of the shoe to the jack and to one of the cutters; and i Fig. 5 is a perspective view of the heel seat portion of a shoe upon which the heel seat fitting operation has been performed by the machine of the present invention.

The machine, as illustrated, is provided with a base 10 having formed therein a rlideway 12 in. which is movably mounted a jack 14 provided with a concave upper portion 16. At the rear of the machine thereis provided a,pair of standards 18 to the upper portion of which is fulcrumed a lever 20 arranged to be rocked through a treadle 22 and carrying atits forward enda rod 24 to which is pivoted a convex presser member or holddown 26. it will be evident that pressure applied to the heel seat portion of the sole ofa shoe supported upon the jack will result ,in somewhat concavmg the heel seat portionof the shoe, as indicated in Fig. 4, due to the cooperatmg concave and convex surfaces of the ack and the presser member-respectively and their relation to rand crease-entering plates 32, 33 and 34 to be described. This depresses the central part of the heel seat at the same'time offsetting the periphery upwardly relatively to the central part and thus facilitates the removal of a U-shaped portion from the periphery of the tread face of the sole by kn ves movable inwardly substantially in the plane of the tread face.

Supported by the base 10 of the machine.

is a U-shapedtable 30 by which is carried a series of jaws or crease plates 32, 33, 34, having thin edge parts shaped to the sides and In the illus by compression springs 40. Thus the rand crease entering aws may take different positions in accordance with the size and shape of the shoe placed in the machine, and are so located that, having entered the rand crease to engage the inseam, they will support the sole and protect the upper of the shoe during the heel seat fitting operation. The table 30 of the machine is also provided with a series of undercut, straight grooves 42 I in which are slidably mounted carriers 44 for the cutters-or knives 46. In the illustrated machine these carriers or knives are seven in number, there being a single carrier and knife at the rear and three carriers and knives upon each side of the machine. The knives are constructed and arranged to make overlapping cuts and certain of these knives are provided with angular extensions 47 to their cutting edges, for the purpose of cutting the strip of material removed from the tread surface of thmsole-intoa number of chips to facilitate the operation of the knives, and other extensions are provided at the forward edges of the foremost knives for the purpose of forming a pair of shoulders at the forward extremities of the beveled portion against which the breasFcorners' of the heel may be positioned. As indicated inFigs. 1 and 2, the table 30 of the machine is provided with still another pair of grooves 48, curved instead' of straight, and intended to be used alternatively with the foremost grooves 42 to support carriers and knives arranged to have the osition of their cutting edges varied longitudinally .of the sole and angularly with respect to the longitudinal axis of the sole so as to travel upon an arcuate path, these knives being used, as shown in Fig; 3, when it is desired to perform the heel seat fitting operation upon a shoe which is'to be fitted with a heel requiring a curved breast out While the foremost carriers and knives traveling in a strai his path, are to be use 7 when the heel seat l itting operation is to be performed upon a shoe having a heel requiring a straight breast cut. The pair of knives and carriers not to be used are, of course, re-

- moved from the machine.

Suitable mechanism is provided for oper-. ating the knives or cutters. As shown in Fig. 4, the rearmost carrier is provided with a pair of downwardly extending lugs 50 arranged to receive the end of a bell'crank lever 52 rigidly mounted upon a shaft 54 and rocked in the operation of the machine by means of a cam 56 keyed to a shaft 58. Loose upon shaft 58 is a pulley 60 driven from any suitable source of power and arranged to be connected to the shaft 58 by any desired form of one revolution clutch, as indicated diagrammatically at 62. The shaft 58 is connected by suitable gearing 68 with apair' of shafts 66, one upon each side of the machine, and the carriers and knives at the sides of the machine are driven from these shafts in a manner similar to that by which the rearmost knife and carrier are operated from shaft 58. A suitable spring 70 is provided, anchored at one end to the frame of the machine and at the other end;

to the bell crank lever 52 and operating to withdraw the rearmost knife at the conclusion of its out. Springs 72 are provided to perform the same function with respect to the other knives. As indicated in Figs. 1 and 2, the knives 46 carried by the foremo:t carriers 44 are pivoted thereto as at 74 about an axis generally parallel to the edge of the sole for movement in a plane substantially parallel to the tread face of the sole and are provided with rearward extensions 7 6 normally held in the position indicated in Fig. 1 by compression springs 78. Each of these knives isalso provided with an upwardly extendingiinger to which is connected, as by a suitable loose joint 82, the end of a rod 84. This rod is longitudinally movable with respect to a sleeve 86 suitably supported by the table 30 as by a. rod88, on which is slidably mounted a sleeve87'to which sleeve 86 is pivoted. The rod 84 is illustrated as screw threaded at its outer end and carries a nut 188 adjustable alcng the screw-threaded portion. This not is carried in such position that after the knife has commenced to bevel the heel seat portion of the sole of the shoe the nut will contact with the sleeve 86 and thus the cutting edge of. the knife will be rocked upwardly, this action assisting in the cutting of the sole in-the desired manner to form at the-heel breast line a shoulder progressively diminishing in height inwardly mm the edge of the sole. By the adjustment of the nut the extent or form of the bevel also may thus be varied.

. iVhen the heel seat fitting operation is to be performed upon a shoe to which a heel requiring a curved breast cut is to be attached, the foremost knives and carriers of Fig. 1 are replaced by the knives and car riers which travel in a curved path. The sleeves 86 may then be adjusted along the rods 88 so that they will be in the proper position to engage the fingers 80 of those knives, the'operation of the machine under these circumstances being facilitated by the pivoting of sleeves 86 to sleeves 87 and cramping being thereby avoided.

The knives other than the foremost pair are illustrated as being of a curved formation and adjustahly connected as by screw the desired bevel may be formed about the heel seat portion of the shoe without an ex:

carriers. This is illustrated in Figs. 1 and 4 in connection with the rearmost knife, and serves as an aid in adjusting the knife in accordance with the size of shoe to be operated upon.

In using this machine to perform the heel seat fitting operation, the operative fnst places the heel in the position, which it should occupy upon the sole of the shoe and makes a mark in conformity with the breast of the heel, as indicated at 100in Fig. 3. He then places the shoe upon the jack, the crease plates 32, 33, 34, entering the rand crease of the shoe, and the mark 100 being placed in alinement with marks 200 or 300 upon the jaws 32 and 34 according as the heel is a heel requirin a straight or a curved breast cut, such placing permitted by reason of the adjustable back plate and the independently adjustable side plates. Then by depressing the treadle 20 the presser member or holddown 26 is brought down upon the heel seat portion of the sole of the shoe thereby slightly distorting the periphery of the heel seat. With the shoe in this condition, the clutch is tripped and the knives are operated in sequence to perform the cuttin operation. In the illustrative machine, the timing of'the knife operating cams is such that the rearmost knife is operated first, then the two knives of the pair adjacent thereto, then the intermediate knives and then the forward knives; At the same time that the forward knives cuttheir portions of the bevel they also, by reason of the angular formation of their cutting edges, are arranged to form the shoulders at the forward portion of the heel seat and against which the breast corners of the heel are to be abutted.

While the invention has been shown and described as embodied in a particular machine it should be understood that this is for purposes of illustration only, and with out intent of limitation thereby.

and a pair of cutters moving inwardly from opposite sides of the sole for trimming the rear end of .the sole adjacent; to the heelbreast line to provide'shoulders adapted to co-operate with corres onding portions of a heel to be attached to t e shoe.

form ad- 52. A'h'eel seat fitting machine for operating upon the sole of a shoe having, in combination, a cutter for forming a shoulder at the breast line of the sole, said cutter being disposed outside of the lateral edge of the sole and mounted for traversing movement with respect to the sole, and guiding means for controlling said traversing movement in a manner to cause said shoulder on the sole to be curved in the plane of the sole.

53. lln a sole trimming machine, in combination,,a trimming cutter, and a pair of guides of dillerent, curvature constructed and arranged to be used alternatively to guide said trimming cutter transversely of ashoe sole at the heel breast line to make alternative cuts of different curvature at the breast line of the sole to conform to the curvature of the breast of a given heel to be attached to said sole.

to travel in a curved path as it makes the breast cut in the sole, and means for trimming surplus material from the periphery of the heel seat of the sole.

55. A heel seat fitting machine having, in combination, a knife arranged to make a breast cut in the sole of a shoe, means for causing any point in the edge of the knife to move in a path curved about an axis substantially perpendicular to the soleof the shoe as the knife makes the breast cut, and means for trimming surplus material from the periphery of the heel seat of the sole.

56. A heel seat fittingmachine having, in combination, a knife arranged to make a breast cut in the sole of a shoe, and means for causing the knife to travel alternatively in either a straight or a curved path as it makes the breast cut in the sole.

57. A heel seat fitting machine having, in combination, a knife arran ed to make a breast cut in the sole of a s 0e, and means for moving the knife laterally of the sole substantially at right angles to the sole of the shoe to cause the cutting edge of the knife to move in a curved path as it makes the breast cut. i

58. A heel seat fitting machine, having, in combination, a pair of knives arranged to make breast cuts at the opposite edges of the sole of a shoe, means for moving the knives laterally of the sole, and means for swinging each knife about an axis substantially at right angles to the sole oi theshoe to cause the knives to move in correspondingly curved paths as they approach each other ,sfrom opposite edges of the select the shoe. H

59. A heel seat fitting machine having, in

combination, a knife formed with two intersecting cutting edges at an angle to one an-..

other, and means for causing the knife to travel laterally of the sole of a shoe operable to cause the knife to make a breast cut alternatively straight or curved as it passes into the sole of the shoe.

60. A heel sea-t fitting machine having, in combination, a cutter arranged to form a shoulder in the sole of a shoe adjacent to the heel breast line'movably mounted for trav: ersing movement with respect to the sole, and means for guiding said cutter in its traversing movement in a path curved about an axis forward of the heel breast line to cause the cutter to form a curved shoulder corresponding to the curvature of the breast of the heel to be attached to the shoe.

61. A machine for trimming and. beveling the periphery of the heel seat portion of a sole to prepare the sole for the reception of a wood heel havin in combination, a pair of clamping mem ers formed and arranged to engage opposite surfaces of the central portion of the heel seat of the sole and to clamp and distort the heel seat por tion of'the sole, and cutting means arranged to bevel the distorted heel seat of the sole while it is thus clamped.

In testimony whereof I have name to this specification. Y
